...Toby's statement, (''Walk away from your marriage if someone sexier comes along' is a message that is really really popular especially in the Blue States,") put me in mind of the following Mishnah:
"The School of Shammai rules: A man should not divorce his wife unless he discovers in her an immoral matter... The School of Hillel holds: [He may divorce her] even if she burnt his meal... Rabbi Akiva says: Even if he found another more beautiful than she." [emphasis mine]
At least all those supposed blue-state philanderers can take comfort in the fact that Rabbi Akiva does not disaprove of their behavior.
